“…The cricothyroid view lies between the cricoid cartilage and thyroid cartilage, with its leading practical utility being to locate the cricothyroid membrane, which is perforated during a cricothyrotomy ( Figure 5 ). Another way to identify the cricothyroid membrane is using the TACA protocol (thyroid–airline–cricoid–airline) with the probe in the transverse plane [ 48 ]. By ultrasound scanning in the sagittal plane, the thyroid cartilage can be visualized from a superficial to deep depth as the sample moves toward the cricothyroid membrane.…”

“…Finally, the tracheal rings show some small, well-spaced, intermittent hypodensities. This sagittal image is called “beads on a string” [ 48 ]. Placing the transducer at the suprasternal notch for a transverse view facilitates the tracheal visualization as an inverted U-shaped structure with a smooth mucosal lining marked by an air–mucosa interface.…”

Airway management is a vital part of anesthesia practices, intensive care units, and emergency departments, and a proper pre-operative assessment can guide clinicians’ plans for securing an airway. Complex airway assessment has recently been at the forefront of anesthesia research, with a substantial increase in annual publications during the last 20 years. In this paper, we provide an extensive overview of the literature connected with pre-operative airway evaluation procedures, ranging from essential bedside physical examinations to advanced imaging techniques such as ultrasound (US), radiography, computed tomography (CT), and magnetic resonance imaging (MRI). We discuss transnasal endoscopy, virtual endoscopy, 3D reconstruction-based technologies, and artificial intelligence (AI) as emerging airway evaluation techniques. The management of distorted upper airways associated with head and neck pathology can be challenging due to the intricate anatomy. We present and discuss the role of recent technological advancements in recognizing difficult airways and assisting clinical decision making while highlighting current limitations and pinpointing future research directions.

У пациентов с указанием или подозрением на патологию ВДП и трахеи рекомендуется проведение дополнительного инструментального обследования для оценки вероятности и возможной причины возникновения трудностей при поддержании проходимости ВДП [84][85][86][87][88][89][90] (УДД -4, УУР -С).…”

“…УЗИ ВДП и области шеи является доступным, экономичным, безопасным, неинвазивным методом, позволяющим в кратчайшие сроки получить дополнительную диагностическую информацию, статические и динамические изображения исследуемых структур и обладающим высокой межоценочной надежностью [88][89][90][91]. Сравнительная оценка параметров, измеряемых с помощью ультразвука, с данными КТ выявила высокую корреляцию между данными обоих методов, что подтверждает диагностическую точность УЗИ ВДП [92,93].…”

The review presents the guidelines of the Federation of Anesthesiologists and Resuscitators, revised in 2021. The recommendations are based on a review of publications and current international guidelines of the Society for Difficult Airways (2018, 2020), the American Society of Anesthesiologists (2013, draft-version 2022), the European Society anesthesiologists (2018). The guidelines provide up-to-date definitions of various “difficult airway” situations; modern data on the use of ultrasound technologies in assessing the upper airways and predicting the risk of aspiration based on preoperative ultrasound scanning of the stomach; current evidence on the effectiveness of modern devices for ventilation and tracheal intubation. Algorithms of actions in various situations with anticipated and unanticipated “difficult airways” in patients with different risks of aspiration are proposed. An algorithm for preparing, predicting possible complications and performing tracheal extubation is also proposed. The recommendations presented in the review are aimed at achieving the goal - increasing patient safety during situations of “difficult airways” through the use of the safest and most effective approaches and methods, as well as reducing the risk of complications associated with these situations (death, severe neurological damage, traumatic injuries of the upper airways and trachea, etc.).

“…Therefore, the search for a simple, non-invasive technique that provides a more accurate assessment of the patient's airway still continues. The ideal method is expected to be fast, accessible, simple and non-invasive (11,16,17). Ultrasound is a safe, non-invasive, low-cost, radiation-free and portable device that allows physicians to evaluate airway anatomy.…”

Introduction: Difficult laryngoscopy and intubation are serious problems among critically ill patients in emergency department (ED) so utility of a rapid, accurate and noninvasive method for predicting of these patients are necessary. Ultrasonography has been recently used in this regard and this study was conducted to investigate the correlation of some introduced upper airway ultrasound parameters with difficult laryngoscopy / difficult intubation in patients referred to the ED. Method: In this diagnostic study all patients ≥18-year-old who had an indication for rapid sequence intubation (RSI) were included. Ultrasound parameters including Hyoid Bone Visibility (HBV), Distance from Skin to Hyoid Bone (DSHB), Distance from Skin to Vocal Cords (DSVC), Distance from Skin to Thyroid Isthmus (DSTI), and Distance between Arytenoids Cartilages (DBAC) were measured in all cases. The patients underwent RSI and thereafter the patients’ baseline characteristics, Cormack-Lehane grade, number of attempted laryngoscopy were recorded in a pre-prepared check list and compared with measured ultrasound parameters. The “difficult laryngoscopy” was defined as Cormack-Lehane classification grades III/IV; and need for more than 3 intubation attempts was considered as “difficult intubation”.Results: One hundred and twenty-three patients (52% male) were included of whom 10 patients (8.1%) were categorized as difficult laryngoscopy cases; and just 4 (3.3%) cases underwent more than 3 laryngoscopy attempts who considered as difficult intubation cases. The mean age of the patients in non-difficult and difficult intubation groups were 69.2±15.16 and 68.77±17.37 years, respectively (p>0.05). There was no significant relationship between difficult laryngoscopy and HBV (P=0.381) but has significant correlation with difficult intubation (p=0.004). The DSHB had a significant correlation with difficult laryngoscopy (p=0.002) but its correlation with difficult intubation was not significant (p=0.629). The DSVC and DSTI had a significant relationship with both difficult laryngoscopy (p=0.003 and p=0.001), and difficult intubation (p=0.025 and p=0.001). The DBAC had not significant correlation neither with the difficult laryngoscopy (p=0.142), nor with difficult intubation (p=0.526).Conclusion: The findings showed that ultrasound parameters including soft tissue DSHB, DSVC and DSTI could be proper predictors of difficult laryngoscopy. Also, HBV, DSVC and DSTI may be proper predictors for difficult intubation. But DBAC was not useful in this regard.
